I think making the top-level "yt" import not depend on h5py is definitely
doable.

We import h5py a bunch of places, but we don't actually *need* it for
anything besides reading certain data types and things like hdf5 sidecar
files, which can just fail with an import error.

In fact, the only thing we use in the h5py namespace is "File", so we would
just need to wrap that class.
